METHOD FOR PREPARING A POLYMER-CLAY NANOCOMPOSITE HAVING AN IMPROVED MECHANICAL PROPERTY

摘要

PURPOSE: A manufacturing method of a polymer-clay nanocomposite is provided to secure the excellent thermal property and flame resistant property of the nanocomposite by dispersing organically modified layered clay to a polypropylene polymer resin. CONSTITUTION: A manufacturing method of a polymer-clay nanocomposite comprises the following steps: firstly melt-mixing organic layered clay with maleic anhydride grafted propylene grafted in a weight ratio of 10:90~30:70, using a kneader or an extruder; and secondly melt-mixing the mixture with polypropylene in a weight ratio of 10:90~40:60, using the extruder, to disperse the organic layered clay to a polypropylene polymer resin. The organic layered clay has an impregnated organic compound.
